The TSS command abend occurred during a COMPARE request, the exact syntax of the command entered is this: TSS COMPARE(PRB5) USING(GJKP)

The abend occurs due to incorrectly formed SITRAN entries on both of these users. The SITRAN object has been added to both users without any CICS transaction identified, it has been specified as blank. If you list the users you should see an entry that has no transaction value and looks like this: SITRAN = FACILITY = *ALL*

Resolution:

The SITRAN object should be removed with the command 'TSS REM(xxxx) SITRAN'. If the user is supposed to be executing a transaction at logon to CICS then you can re-add the SITRAN object with the correct value. Once this is done you can run the COMPARE again and it should be successful. You may also want to check other users for a blank SITRAN value and correct as needed. Also note that the abend itself is not harmful other than the possibility of stranding command related storage in the Top Secret address space.
